Two circular coils of radii 5.0 cm and 10 cm carry equal currents of 2.0 A. The coils have 50 and 100 turns respectively and are placed in such a way that their planes are perpendicular to each other, what would be the magnitude of the magnetic field B at the centre ?

Explanation

To find the magnetic field at the center of two circular coils with given parameters, we can follow these steps:

### Step 1: Identify the parameters
- **Coil 1:**
- Radius \( r_1 = 5.0 \, \text{cm} = 5 \times 10^{-2} \, \text{m} \)
- Current \( I_1 = 2.0 \, \text{A} \)
- Number of turns \( n_1 = 50 \)
